When I made my film opening, I did it to say something, so that the audience would have a sense of what you wanted to say, of what you wanted to communicate. I did this through using a series of signs and symbols, such as colour, clothing, camera shots and angles, muse-en-scene.
Semiotics in a nutshell:
This is a study of signs and symbols, there is a sign, an object that is called signifier.
The meaning that is given to that is called the ignited. This is not fixed and can change with time or the society or culture that it is viewed in. And here we have denotation and connotation. Denotation is what you see and connotation is the meaning that you give to what you see e.g white is a symbol for purity and virginity, red is a symbol of love or danger/blood.
Codes and conventions:
There is so much that happens t an unconscious level, or even conscious level, that you are already aware of in your work such as genre, conventions, narrative conventions, codes about camera angles, dark lighting etc. It is not just about you going through those and saying how you used them, what you denoted (the signifier) to create meaning, the connotation that you hope you audience will attribute to them.
Theorists:
Fiske (1982) - "denotation is what is filmed, connotation is how it's filmed"
Saussure (1983) - Audience can look at a media text from a syntactic pointy of view, just describing what they see, or from a representational or symbolic point of view where the attribute meaning to what they see.
Barthes (1967) - An audiences' understanding of media texts comes from heir understanding and knowledge of frequently told myths or stories. He argues that the organisation of signs encodes particular messages and ideologies.
Chandler (2005) - Says that semiotics is important because it helps us not take 'reality' for granted as something that can exist without human interpretation.
Stuart Hall - Argued that meaning is not fixed by the producer, and the audience is not passive, gave us different readings, the proffered reading is where the audience reads it the way that you wanted them to.
ANSWER PLAN
So the media language you use is trying to construct a meaning that you wish the audience to read, and if you are talking about this years work, the language should be consistent across all three products so there is to be a sense of branding and one campaign.
So using the four micro elements, mise-en-scene, camerawork, editing and sound, pick three examples for each where this helps you create meaning and construct the whole representation thing.
You can also talk about the micro elements, genre, narrative, representation and use them as a source of theorists, as they are all relevant.
